A Vehicular Ad-hoc Network (VANET) is a subtype of Mobile Ad-hoc Network (MANET) that is used to provide communications between nearby vehicles and between vehicles and the roadside fixed infrastructure. Due to the unique characteristics of the network routing in Vehicular Ad hoc Networks is a challenging task because the network contains high mobility of nodes, dynamically changing topology and highly partitioned network. The concept of VANETs is quite simple: by incorporating the data sharing capabilities and wireless communication, the vehicles can be turned into a network providing similar services like the ones with which we are used to in our homes or officies. So, VANET is a promising approach for the intelligent transportation system (ITS). The design of routing protocols in VANETs is important and necessary issue for support the smart ITS. This paper represents the topology based routing protocol in VANET. These routing protocols use link’s information that exists in the network to perform the packet forwarding.
